The discontinuities play an important role both in design and development stages of many geotechnical engineering projects. Because of that considerable time and capital should be spent to determine discontinuity sets by conventional methods. This thesis present the results of the studies associated with the application of the Remote Sensing (RS) and the development of a methodology in accurately and automatically detecting the discontinuity sets. For detection of the discontinuities, automatic lineament analysis is performed by using high resolution satellite imagery for identification of rock discontinuities. The study area is selected as an Andesite quarry area in Gölbasi, Ankara, Turkey. For the high resolution data 8-bit Ikonos Precision Plus with 1 meter resolution orthorectified image is used. The automatic lineament extraction process is carried out with LINE module of PCI Geomatica v8.2. In order to determine the most accurate parameters of LINE, an accuracy assessment is carried out. To be the reference of the output, manual lineament extraction with directional filtering in four principal directions (N-S, E-W, NE-SW, NW-SE) is found to be the most suitable method. For the comparison of automatic lineament extraction and manual lineament extraction processes, LINECOMP program is coded in java environment. With the written code, a location and length based accuracy assessment is carried out. After the accuracy assesssment, final parameters of automatically extracted lineaments for rock discontinuity mapping for the study area are determined. Besides these, field studies carried out in the study area are also taken into consideration.

An accuracy assessment methodology for the remotely sensed discontinuities: a case study in Andesite Quarry area, Turkey Kocal, A.; Duzgun, H. S.; Karpuz, Celal (2007-01-01) The discontinuities play an important role in both the design and development stages of many geotechnical engineering projects. Therefore, semi-automatic detection of discontinuities based on remote sensing will save a considerable amount of time and cost. Accuracy of the semi-automatically detected discontinuities is also as important as the detection process, since the results directly reflect the uncertainty in the geotechnical problem. The current paper presents an accuracy assessment methodology for se...
A new concept on sampling systems by air cannon application Yünel, Ufuk; Hiçyılmaz, Cahit; Department of Mining Engineering (2004) The most important criterion in industrial production processes is to control the required product quality and comply with the standards pre-described for the application during any stage of the process. This control begins from the entry of raw material to the plant and continues with pre-determined points. Mainly two different types of inspection and analyses are used to examine the material quality and content. These are physical and chemical analysis.In most of the production plants above mentioned anal...
Development of an algorithm for material selection Seyis, Önder; Atala, Haluk; Department of Metallurgical and Materials Engineering (2005) Material selection is one of the major points that should be taken into account seriously in the engineering design stage. Each material has various properties such as mechanical, thermal, electrical, physical, environmental, optical and biological properties. However, it is a well known fact that only a limited number of design engineers have a thorough knowledge on all these properties of a specific material, which is planned to be used in the manufacturing of the product. Therefore, the design engineer s...
A study on the application of e-commerce in Turkish mining industry Mutlu, Yakıcı İçli; Güyagüler, Tevfik; Department of Mining Engineering (2005) In this thesis, a road map/strategy that must be followed by firms that want to utilize e-commerce facilities is established. For this purpose, road map suggestions that were taken from literature were examined and a road map which can be followed by mining companies is developed. First, a questionnaire was applied to mining firms to understand the attitude of mining sector to e-commerce. Then a firm that had involved in the questionnaire and was interested in e-commerce was selected to work with. The studi...
Three dimensional numerical modelling of discontinuous rocks by using distinct element method Koçal, Arman; Karpuz, Celal; Department of Mining Engineering (2008) Shear strength characterization of discontinuities is an important concept for slope design in discontinuous rocks. This study presents the development of a methodology for implementing Barton-Bandis empirical shear strength failure criterion in three dimensional distinct element code, 3DEC, and verification of this methodology. Normal and shear deformation characteristics of discontinuities and their relations to the discontinuity surface characteristics have been reviewed in detail. First, a C++ dynamic l...
